压缩式致冷设备的电子宽温域多功能控制

Wide Temperature Range and Multi-Function Control for Compression Refrigerating Systems

设计并研制了一种用于压缩式致冷设备的电子式定温域多功能控制装置。它除具有控温范围宽、精度高、控温参数易调等优点外，还实现了低成本的温度显示、半自动除霜控制、加电延时保护、过欠压保护等功能。全部采用无触点控制方式，有良好的性能／价格比。

An electronic control device of wide temperature range with multi-functions used in compression refrigerating systems has been studied and developed with satisfactory results.In addition to the advantages of wide temperature range control, high accuracy and easy regulation in temperature parameter control, it also has the virtues of the realization of temperature display at low cost, semi-auto-defrosting control,time-delay protection during starting and overvoltage protection,All the controls are contactless with high ratio of property to price.
